Masturbation is a common form of auto eroticism, providing sexual pleasure or orgasm in the absence of a partner. The act, when performed with a partner, is called mutual masturbation and is sometimes used as an alternative to sexual intercourse. Masturbation refers to the sexual stimulation of a person's genitals, usually to the point of orgasm. The stimulation can be performed manually, by use of objects or tools, or by some combination of these methods.
